How do you equalize your car stereo ? A flat curve all along the frequency range with a RTA microphone and DSP ?
Pioneer AVH series. It does EQ plus time correction. I dunno' what curve they have it apply, but it sounds pretty solid from the get-go.What head unit you have and what kind of analysis is that ?
How do you make a phase alignment ? My DSP comes with several options for phase (11.25°, 22.5°, 45°, etc), but I do not understand how it worksI do it by ear. Do a phase/time alignment first. Then I play a 20-20khz sine sweep, which will quickly identify any major problem areas. Then I switch to 1/3rd octave banded pink noise tracks and equalize for flat response one channel at a time. Usually takes 3-4 times per channel. Once both channels are flat, I balance for proper staging.
There is some disagreement about phase vs time alignment. Some people would say you don't need phase if you have time alignment.How do you make a phase alignment ? My DSP comes with several options for phase (11.25°, 22.5°, 45°, etc), but I do not understand how it works
You just need the "in phase/out-of-phase" test track.You're a "better ear than I" if you can do the phase alignment by ear. While I know that there is an issue, I'm not sure what it is until the computer tells me so. That's jus me though.
My test tracks are ancient- the old Iasca SQ competitors disc & My Disc by Sheffield labs. Autosound 2000 had 3-4 disc series, and My Disc is one of them. There's alot of them out there, but as auto tuning becomes more reliable, I imagine tuning will become a lost art. If you get the right disc's they have liner notes telling you how to use the tracks, so it's easy to teach yourself.Just started using DSP so that is good to know. Not every system I help with has DSP and softeware to check that out. Looked online, is there a CD or app (download) you recomend?
